Anthurium plant named `Baby Pink`

ABSTRACT

A distinct cultivar of Anthurium plant named `Baby Pink`, characterized by its compact, upright, outwardly arching and very freely clumping growth habit; dark green leaves that are ovate to sagittate in shape; strong vigorous roots; numerous inflorescences that are positioned above the foliage on strong and erect scapes; durable soft pink spathes; year-round continuous flowering; and good post-production longevity.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum, and hereinafter referred to by the cultivar name `Baby Pink`.

The new Anthurium is a product of a planned breeding program conducted by the Inventor in Schipluiden, The Netherlands. The objective of the program is to create new compact Anthurium cultivars that are suitable for smaller containers and that have a freely clumping growth habit, strong plant growth, attractive spathe color, numerous inflorescences and leaves, and good post-production longevity.

The new Anthurium originated from a cross by the Inventor on Jan. 24, 1994 of the Inventor's proprietary Anthurium andreanum selection code number 9419 as the female, or seed, parent with the Inventor's proprietary Anthurium andreanum selection code No. 923 as the male, or pollen, parent. The cultivar `Baby Pink` was discovered and selected by the Inventor as a plant within the progeny of the stated cross in a controlled environment in Schipluiden, The Netherlands in the autumn of 1995.

Asexual propagation of the new cultivar by tissue culture in a laboratory in Belgium has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

The new Anthurium has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of the cultivar `Baby Pink`. These characteristics in combination distinguish `Baby Pink` as a new and distinct cultivar:

1. Compact, upright, outwardly arching and very freely clumping growth habit.

2. Dark green leaves that are ovate to sagittate in shape.

3. Strong vigorous roots.

4. Numerous inflorescences that are positioned above the foliage on strong and erect scapes.

5. Durable soft pink spathes.

6. Year-round continuous flowering.

7. Good post-prduction longevity.

The new Anthurium can be compared to the female parent, the Inventor's proprietary selection code number 9419. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of selection code number 9419 in the following characteristics:

1. Plants of the new Anthurium have pink-colored spathes whereas plants of the selection code number 9419 have red-colored spathes.

2. Plants of the new Anthurium are more compact than plants of the selection code number 9419.

3. Plants of the new Anthurium have more durable leaves than plants of the selection code number 9419.

4. Plants of the new Anthurium are more freely clumping than plants of the selection code number 9419.

The new Anthurium can be compared to the male parent, the Inventor's proprietary selection code number 923. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of selection code number 923 in the following characteristics:

1. Plants of the new Anthurium have lighter pink-colored spathes than plants of the selection code number 923.

2. Plants of the new Anthurium are more compact than plants of the selection code number 923.

3. Plants of the new Anthurium are more freely clumping than plants of the selection code number 923.

4. Plants of the new Anthurium have much smaller leaves than plants of the selectin code number 923.

5. Plants of the new Anthurium have smaller spathes than plants of the selection code number 923.

The new Anthurium can be compared to the Anthurium cultivar `Champion` disclosed in U.S. Plant Pat. No. 9,088. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of the cultivar `Champion` in the following characteristics:

1. Plants of the new Anthurium are more compact than plants of the cultivar `Champion`.

2. Plants of the new Anthurium are more freely clumping than plants of the cultivar `Champion`.

3. Plants of the new Anthurium have smaller and more durable leaves than plants of the cultivar `Champion`.

4 Plants of the new Anthurium have more durable spathes than plants of the cultivar `Champion`.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Anthurium, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph on the first sheet comprises a top perspective view of a typical potted plant of the cultivar `Baby Pink`.

The photograph on the second sheet comprises a close-up view of a typical spathe and spadix of the cultivar `Baby Pink`. Leaf, spathe and spadix colors in the photographs may appear different from the actual colors due to light reflectance.
